Security update for openssl-3 SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2023:4635-1 Final 1 1 2023-12-02T11:57:22Z current 2023-12-02T11:57:22Z 2023-12-02T11:57:22Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for openssl-3 This update for openssl-3 fixes the following issues: - CVE-2023-5678: Fixed generating and checking of excessively long X9.42 DH keys that resulted in a possible Denial of Service (bsc#1216922). Bug fixes: - The default /etc/ssl/openssl3.cnf file will include any configuration files that other packages might place into /etc/ssl/engines3.d/ and /etc/ssl/engdef3.d/. - Create the two new necessary directores for the above patch.

Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an excessively large P, it doesn't check for an excessively large Q. An application that calls DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_pub_key_ex(), EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line application when using the "-pubcheck" option, as well as the OpenSSL genpkey command line application. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.
